Abstract:
PROBLEM TO BE SOLVED: To provide a method and a composition for detecting a target in a sample. SOLUTION: A method for quantifying the target comprises forming a reaction mixture comprising a sample possibly containing the target, a codable label, one or more target-specific probes each of which binds specifically to the target under selective binding conditions, and a separating portion; treating the reaction mixture under reaction conditions such that a detectable complex is produced when the target is present, wherein the detectable complex includes the codable label, the target-specific probe and the separating portion; and counting the number of codable labels to quantify the target.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for labeling a molecule by contacting a sample molecule with a solid support coupled to a chemical group comprising a cleavable functional group, one or more functional groups and a reactive group under conditions allowing the sample molecule to covalently bind to the reactive group on the sample molecule, and cleaving the cleavable functional group to release the sample molecule comprising the one or more functional groups (which can be a tag). SOLUTION: The solid support is covalently coupled to a chemical group comprising a cleavable functional group, a mass spectrometry tag and a reactive group for covalently attaching a sample molecule, wherein the cleavable functional group, the tag and the reactive group are arranged relative to one another to allow transfer of the tag to the sample molecule upon cleavage of the cleavable functional group.

Abstract:
A capillary electrophoresis element is disclosed. The elements includes a capillary electrophoresis tube containing a low-voscosity polymer solution having a selected mesh size and low-solution viscosity. The mesh size may range from 50-100 ANGSTROM , for separating single-stranded oligonucleotides, to up to 300 ANGSTROM or greater, for separating relatively large duplex DNA fragments or proteins. Also disclosed is a method for formulating a low-viscosoty electrophoresis separation medium having a selected mesh size.
Abstract:
An assay card and devices and methods for isolating chambers on the assay card are described. The assay card comprises a substrate formed of one or more materials, e.g., plastic, having a softening temperature, the substrate defining channels communicating with respective reaction chambers. The assay card may be heated in a region of the channels to at least the softening temperature. The softened plastic may be deformed, e.g., with a tool which may or may not also provide the heat for softening the substrate. In this manner, the plastic of the substrate may be caused to at least partially obstruct the channels, thereby isolating the reaction chambers. The invention also relates to a method of manufacturing a tool device that includes pins for heating and deforming an assay card.

Abstract:
A device for performing biological sample reactions may include a plurality of flow cells configured to be mounted to a common microscope translation stage, wherein each flow cell is configured to receive at least one sample holder containing biological sample. Each flow cell also may be configured to be selectively placed in an open position for positioning the at least one sample holder into the flow cell and a closed position for reacting biological sample contained in the at least one sample holder. The plurality of flow cells may be configured to be selectively placed in the open position and the closed position independently of each other.
